Don't Buy the Seller

“I bought an item online from a killer.”

Jang Soo-hyun (Shin Hae-sun) has just moved into a new house in South Korea, and the used washing machine she buys through a second-hand app doesn't work. She leaves an angry comment calling the seller Joo Cheol-ho (Kim Sung-kyun) a con man, then reports him to the police. Park Hee-kon follows what comes next: obscene phone calls, food deliveries nobody ordered, strangers at her door, and the plain fact that anyone online can learn where you live.
